win32: one window procedure for every video and input driver

Browse Source 
gfx/common/win32_common.c exported twelve window procedures: one for
each video family - Direct3D, WGL, Vulkan, GDI - times each kind of
input driver - DirectInput, raw input, any other. Each video driver
chose its three by comparing the input driver's name. Underneath were
three procedures that were the same long switch, copied, with a few
cases different in each.

There is one procedure now, win32_window_proc().

- What it does with a message is decided in one place,
  gfx/common/win32_msg_route.h: for a message and the kind of input
  driver in use, the steps to take - an IME step, a key step, the
  cursor clip, an offer to the input driver, the window's own
  business, a display change - which the procedure carries out in
  that order. The three switches are gone; what each did is the route
  for its kind.
- A video family differs from another only in what creating the
  window sets up, and GDI in painting from the procedure. A video
  driver says which family its window is with
  win32_window_proc_setup() before creating it.
- The kind of input driver is read from the setting in that one
  function, at the moment each video driver used to read it. Nine
  video drivers and contexts lose their comparison of the input
  driver's name.

Behaviour is meant to be unchanged, message for message. The header
takes no Windows types, and samples/gfx/win32_msg_route holds it to
the three switches, which are written out in the test as they stood,
case list for case list and #if for #if: for every message, with and
without the hotplug timer's id in wparam, on the desktop and on the
Xbox, with and without threads, the route is the steps the old switch
took. The message numbers the header spells out are checked against
the SDK's when win32_common.c is compiled.

One oddity is kept on purpose, so that the comparison is exact: with
an input driver, the hotplug timer's id is looked for under the timer
message and also under the eight messages the switches happened to
list before it.

Compiled for Windows with mingw: win32_common.c with and without the
two input drivers and with every family, the Vulkan and WGL contexts,
and the GDI, Direct3D 8, 9 (HLSL) and 10 drivers. The Direct3D 11 and
12 drivers do not build against this mingw's headers for reasons that
have nothing to do with this change, and the Cg driver needs Cg; their
edit is the same three lines. Not run on Windows.

win32_common.c goes from 2904 lines to 2602.

# What the Win32 window procedure does with a message.
# gfx/common/win32_common.c had twelve window procedures, one
# for each video family times each kind of input driver,
# built on three copies of one long switch. They are one
# procedure now, which asks win32_msg_route() what to do with
# a message. The three switches are written out in the test
# as they stood, and for every message - with and without the
# hotplug timer's id, on the desktop and on the Xbox, with
# and without threads - the route must be the steps the
# switch for that kind of input driver took. Raw input's
# keys made into keyboard events a second time, which is
# what routing them like another driver's would do, is put
# back and asserted to be caught.

*
* There used to be twelve window procedures: one for each video family
* (Direct3D, WGL, Vulkan, GDI) times each kind of input driver
* (DirectInput, raw input, any other), built on three copies of one
* long switch that differed in a few cases each. A video driver chose
* its procedure by comparing the input driver's name.
*
* There is one procedure now, and this says what it does. For a
* message and the kind of input driver in use, win32_msg_route()
* answers with the steps to take, which the procedure carries out in
* a fixed order:
*
* IME, key, clip, input, common, display - then DefWindowProc.
*
* Any step may answer the message and end it there, as marked below.
* The three switches are gone; what each did is the route for its
* kind, and samples/gfx/win32_msg_route holds the routes to the
* switches they replace, message by message.
*
* No Windows types, so that the sample can build it on a host. The
* message numbers are Windows' own, spelled out; win32_common.c checks

/* win32_msg_route_test.c -- what the Win32 window procedure does with
* a message, held to the three switches it replaced.
*
* gfx/common/win32_common.c had three window procedures that were one
* long switch each - for the DirectInput driver, the raw input driver,
* and any other - and twelve exported ones built on them. They are one
* procedure now, which asks win32_msg_route() what to do with a
* message.
*
* The three switches are written out below as they stood, case list
* for case list and #if for #if, each returning the steps its case
* took. The claim:
*
* For every message, with and without the hotplug timer's id in
* wparam, on the desktop and on the Xbox, with and without threads,
* win32_msg_route() gives the steps the old switch for that kind of
* input driver took.
*
* A sabotage mode routes one message the way another kind's switch did
* - raw input's keys made into keyboard events here, which would give
* every key press twice - and is asserted to be caught. */
